Abstrakt: The process of indirect cathodic amination of benzene is studied in aqueous media containing 4-10 M HSO and, accordingly, 13.8-7.1 M CHCN. At 50°C, electrolysis in the system of Ti(IV)-NHOH-CH results in formation of aniline and also small amounts of isomeric phenylenediamines and diphenyl. The current efficiency of aniline is maximum in the catholyte containing 8 M HSO and 9.4 M CHCN. Under these conditions, full conversion of hydroxylamine is observed; the 80% current efficiency of aniline corresponds to the efficiency of the amino radical source and its mass fraction among the products of electrolysis exceeds 97%.
